Abstract. Ernobius kadleci sp. nov. ( species-group) from Cyprus is described and compared with similar species.

Introduction

In the last year I have described two new Cyprian species from the genus Ernobius C. G. Thomson, 1859, and I gave a key to all six Ernobius species from Cyprus including both new species (Zahradník 2013). Now I treated some other material, where I found a further new Ernobius species from Cyprus.

TAXONOMY

Ernobius kadleci sp. nov. (Figs. 1-3)

Type material. Holotype (♂): Cyprus, Akamas peninsula, 5 km W of Latsi, 1.-10.iv.2000, S. Kadlec lgt., (PZPC). Paratypes (2 ♂♂, 4 ♀♀): the same data as holotype, (PZPC).

Description. Male (holotype). Lengthily elongate-elliptical, transversally slightly convex, body length 2.9 mm, the greatest width 1.1 mm. Ratio elytra length : elytra width of 1.8. Yellowish-brown, including antennae, palpi and legs. Head slightly convex, shining with two types of punctures - the first ones very fine and dense, almost touching each other, the second ones umbilicate, coarse and also dense, distance between punctures the same as their diameter. Clypeus transversally depressed. Eyes small, globular, without hairs. Front 3.1 times wider than width of eye in dorsal view. Antennae filiform, consisting of eleven antennomeres. The 1st antennomere robust, 1.9 times longer than wide, the 2nd antennomere shorter and slimmer than the 1st, 1.8 times longer than wide,

233 moderately shorter than the 1st. The 3rd 1.6 times longer than wide, 0.9 times shorter than the 2nd. The 4th and the 5th the same in length, the 4th slimmer than the 5th, shortly longer than wide. Antennomere 6 - 8 very short, transverse; these three antennomeres together shorter than 3rd - 5th antennomeres. The last three antennomeres very long and slim, together longer than 1st - 8th antennomeres. The 9th and 10th same in length, 7 times longer than wide, the last antennomere the longest, slightly slimmer than previous two antennomeres, 9 times longer than wide (Fig. 2a). The last segment of maxillary palpi slightly clubbed, 2.5 times longer than wide on apex. Pronotum transverse, ratio length : width 0.7, the widest in the second third, strongly arcuate to apex, slightly narrowed to base of pronotum. Anterior and posterior angles from lateral view rounded (Fig. 3). Transversal furrow before base of pronotum missing. Surface of pronotum shining, densely and coarsely umbilicate punctuate, distance between punctures equal to or smaller than their diameter. Pubescence silver-white, long, fine, recumbent, inclined backwards, on the posterior angles obliquely backwards. Scutellum small, triangular, shortly longer than wide, with shallow longitudinal furrow.

Figs 1-3. Ernobius kadleci sp. nov.: 1- aedeagus; 2- antennae - a - male, b - female; 3- pronotum.

234 Elytra lengthily elongate, without distinct shoulders, shining, densely and coarsely punctuate; diameter of punctures 2 - 3 times smaller than distance between them. Pubescence silver-white, fine, dense, shorter than on pronotum recumbent or slightly semierect, inclined backwards. Legs thin and long, with sparse long recumbent pubescence. Tibiae slightly shorter than tarsi. The 1st tarsomere the longest, the 2nd 1.4 times shorter than the 1st, the 3rd twice shorter than the 1st, and the 4th 2.1 times shorter than the 1st, deeply heart-shapedly emarginate up to half its length, in this emargination the 5th tarsomere is inserted, which is lengthily oval, almost slightly clubbed, 4 times longer than wide. Claws small, without teeth. Aedeagus asymmetrical, see Fig. 1. Female. (Allotype). Of the same length as male, antennae shorter and more robust, antennomeres 6 - 8 not transverse, the same length as wide. The last three antennomeres long and slim, together longer than 1st - 8th antennomeres. The 9th and 10th of same length, 4 times longer than wide, the last antennomere the longest, slightly slimmer than previous two antennomeres, 6 times longer than wide (Fig. 2b).

Variability. Specimens from the type series without visible differences, vary only in the body length from 2.8 to 3.1 mm. Differential diagnosis. The species belongs to the nigrinus species-group. It differs from the other species in this species-group (and also from other species-groups) by the shape of the aedeagus. It is very similar to Ernobius benedikti Zahradník, 2012, from which differs by more robust body, less globular eyes, longer antennae and shorter pubescence on elytra. Name derivation. Dedicated to the collector of the type material and my friend Stanislav Kadlec (*1948 - †2008), well-know specialist of Cerambycidae and Melandryidae.
